Encrypt 加密练习

        System.out.println(string2);
        Assert.assertEquals(string,string2);

        String str="hello word";
        String base16= Hex.encodeToString(str.getBytes());
        System.out.println(base16);

        System.out.println(str2);
        Assert.assertEquals(str,str2);


        //散列算法加密
        String saltstr="hello word";

        hashService.setPrivateSalt(new SimpleByteSource("555555"));//设置私有盐
        hashService.setGeneratePublicSalt(true);//生成公盐 默认false
        hashService.setRandomNumberGenerator(new SecureRandomNumberGenerator());//生成公盐
        hashService.setHashIterations(1);//设置散列迭代次数
        HashRequest request=new HashRequest.Builder()

        String hex=hashService.computeHash(request).toHex();
        System.out.println(hex);


        //AES算法
        AesCipherService aesCipherService=new AesCipherService();
